Hello,
this is my first Post. I am learning Shopify Theme-Dev. for abour two weeks now.
I wanted to ask, if it is possible to add transparent colors in Shopify (Dawn Theme) because
the solid colored boxes I do not like. I already saw, that with Dawn 1.1.0 there were changes
made to the colors (base.css) but I did not fully understand it.
Plus I do not know how to manually update my Dawn theme from 1.0.0 to 1.1.0 manually as
there is no “Update Theme Button anywhere” 
Thank you for the help, have a sunny day
Gregor
